STOCKHOLM (UPDATED) - Per Gessle will participate in a concert the free tabloid newspaper Metro is organizing to celebrate its 10th anniversary on September 7.

The event, "The Concert of the Decade" as Metro not-so-humbly calls it, will take place at the Globe Arena, Stockholm, and – along with Gessle – will feature The Cardigans and Petter among others. "I thought I'd air out the band," Per tells TDR, "Nothing big, maybe four or five songs…" TV3 will broadcast the concert the very same week.

One thousand tickets will be given away via Metro, TV3, Rix FM and NRJ. They can be also purchased via Ticnet, regular price 250 kronor (€29), for Metro club members 125 kronor.

Update Jul 26: Three more acts have been revealed: Eva Dahlgren, Eric Gadd and Robyn.

Update Aug 28: Swedish TV3 will broadcast the show September 10 at 17:30 CET. Also, The Hives and Darin have been added to the bill

Update Aug 29: The final two acts are The Ark and Håkan Hellström. Today, nine days before the concert, TicNet still shows availability "green" and you can still get tickets reserved for Metro members only. MTG (owners of Metro) has made tickets available for other MTG members as well, like Club Rix FM.
